Underwater stationary targets are objects under the water that can¡¦t move autonomously. Apparatus feasible for detecting underwater stationary targets includes: optics, acoustics and geophysical instruments. The objective of this study was to investigate engineering characteristics of the battleship reef and other reefs deployed off Hai-Kou, Ping-Dong County, by the application of an integrated underwater surveying system. A total of four surveys were conducted. i.e., the 14th of April 2004, the 20th of July 2006, the 3rd of Mar. 2007 and the 30th of Oct. 2007. The investigation were completed using primarily the sidescan soner, along with other auxiliaries such as magnetometer and single beam echo sounder. Based on a mutual consideration of the results of the first survey in April 2004, the battleship on the seafloor was identified as Jong-Rong battleship. The battleship was sitting on the seabed in an upright condition at depths of 32 to 42m below the sea surface. A chain cable was catenated from the stern of the battleship down to the seabed. In addition, a large number of cubic artificial reefs were spreaded around. A comparision of results obtained during the first and the third survey indicated that the battleship was undergone a displacement of 250m. The significant displacement of the battleship was correlated with a medium magnitude typhoon passed by on the 3rd of Dec. 2004 and the 17th of May 2006 (i.e., Nanmadol and Chanchu Typhoon). The second and the third survey indicated that the battleship was¡¦t moved by earthquake on the 26th of Dec. 2006 (i.e., Herng Chuen earthquake)with magnitude of seven. A comparison of the third and the fourth surveys suggested that the battleship¡¦s bow was moved to the north for an extra 20m. This movement is correlated with a typhoon passed by in Aug. 2007(i.e., Pabuk Typhoon). However, a detailed investigation of the sonographs indicated that there are very limited relative displacement between the battleship and cement artificial reefs that scattered around the battleship. Therefore, further investigations are needed to verify this tautative conclusion. Based on sidescan soner imagery collected in four surveys between 2004 and 2007. the location of various type of artifical reefs at Hai-Kou artifical reef site were investigated. Except the battleship reef, all the orther types of reefs which include steel reef, electric-pole reef and cement reef were not displaced by either typhoon or earthquake. Under the influence of typhoon waves, the battleship reef was displaced for a distance of 250m.

Shading devices are frequently used to control solar gain through windows. Solar optical properties are very important in the energy analysis of windows. Transmittance, absorptance and reflectance are required to quantify solar heat gain through complex fenestration systems, which consist of combinations of glazing and shading layers. In this research the solar transmittance of a sheer blind was measured using a Broad Area Illuminating Integrating Sphere (BAI-IS). More specifically, the spectral directional-hemispherical transmittance was measured in the wavelength range of 0.4 µm to 2.0 µm. A “sheer blind” consists of soft fabric vanes, similar to a venetian blind, suspended between two vertical layers of sheer fabric. This arrangement is popular because it is attractive and it has potential application for daylighting. The vertical sheer fabric reduces the solar intensity and diffuses incident radiation; generally reducing solar gain and producing soft, natural illumination. The fabric vanes control the amount of light entering the room. Shading devices such as venetian blinds, sheer blinds and drapes have spatially non-uniform and light scattering surfaces. Hence, measurement error occurs if the solar optical properties are measured by traditional narrow-beam measurement techniques typically used in commercial spectrophotometers. To reduce this error, a BAI-IS is recommended. The BAI-IS apparatus consists of a 20-inch diameter integrating sphere, sample mounting system, monochromator, radiant source, lock-in-amplifier, photo sensor, optical chopper and various auxiliary devices. In order to improve reliability of the measurement the BAI-IS has recently been upgraded by replacing most of the key control and measurement equipment. The refurbishment of the BAI-IS apparatus was successful. The directionalhemispherical transmittance of a sheer blind from BAI-IS measurement was found to agree well with an analytical model.

This thesis includes seven short stories and a critical afterword. The afterword places the stories in their literary historical context in regards to creative nonfiction. It goes on to discuss the craft of fictionalizing autobiographical stories. Each of the stories should stand alone, though they follow the narrator's life for a number of years. Harlin Anderson is the narrator of all the stories.

Being in the era of information technology, importance and applicability of analytical statistical model an interdisciplinary setting in the modern statistics have increased significantly. Conceptually understanding the vulnerabilities in statistical perspective helps to develop the set of modern statistical models and bridges the gap between cybersecurity and abstract statistical /mathematical knowledge. In this dissertation, our primary goal is to develop series of the strong statistical model in software vulnerability in conjunction with Common Vulnerability Scoring System (CVSS) framework. In nutshell, the overall research lies at the intersection of statistical modeling, cybersecurity, and data mining. Furthermore, we generalize the model of software vulnerability to health science particularly in the stomach cancer data. In the context of cybersecurity, we have applied the well-known Markovian process in the combination of CVSS framework to determine the overall network security risk. The developed model can be used to identify critical nodes in the host access graph where attackers may be most likely to focus. Based on that information, a network administrator can make appropriate, prioritized decisions for system patching. Further, a flexible risk ranking technique is described, where the decisions made by an attacker can be adjusted using a bias factor. The model can be generalized for use with complicated network environments. We have further proposed a vulnerability analytic prediction model based on linear and non-linear approaches via time series analysis. Using currently available data from National Vulnerability Database (NVD) this study develops and present sets of predictive model by utilizing Auto Regressive Moving Average (ARIMA), Artificial Neural Network (ANN), and Support Vector Machine (SVM) settings. The best model which provides the minimum error rate is selected for prediction of future vulnerabilities. In addition, we purpose a new philosophy of software vulnerability life cycle. It says that vulnerability saturation is a local phenomenon, and it possesses an increasing cyclic behavior within the software vulnerability life cycle. Based on the new philosophy of software vulnerability life cycle, we purpose new effective differential equation model to predict future software vulnerabilities by utilizing the vulnerability dataset of three major OS: Windows 7, Linux Kernel, and Mac OS X. The proposed analytical model is compared with existing models in terms of fitting and prediction accuracy. Finally, the predictive model not only applicable to predict future vulnerability but it can be used in the various domain such as engineering, finance, business, health science, and among others. For instance, we extended the idea on health science; to predict the malignant tumor size of stomach cancer as a function of age based on the given historical data from Surveillance Epidemiology and End Results (SEER).

The quality of convective precipitation and storm prediction is dependent on the level of knowledge of the convective environment. Convective environment characteristics describe various conditions in the atmosphere which are suitable for the convective storm formation and evolution. The characteristics CAPE, wind shear S01, S03 and S06 were selected for the discussion of their properties and predictive ability. This master thesis deals with the CAPE and S0X values analysis in the Czech Republic during the period May-August 2005-2011. Furthermore it analyzes the distribution of the combined characteristics CAPE × S0X and index NDSEV, especially in the critical interval of values which indicate a storm occurrence. It also deals with the estimation of relationship between NDSEV index and the heavy precipitation occurrence in the Czech Republic. The verification criterion CSI was applied to the evaluation of various threshold values for the NDSEV index.

Semantic-Representation-Provenance-Contextual-Information-Scientific-Research Die Computer- und Informationstechnologie ist eine der größten Errungenschaften des letzten Jahrhunderts -- eine Revolution, welche die Art und Weise beeinflusst, auf die wir im täglichen Leben auf technische und soziale Problemen reagieren. Obwohl diese Technologien bereits Forschungsaktivitäten an sich beeinflussen, so ist zu erwarten, dass sie auch einen Einfluss auf das Publizieren und Teilen von Forschungsergebnissen haben werden. Bisher wurden in wissenschaftlichen Publikationen nur in geringem Maße Daten beigefügt. Forschungförderungseinrichtungen drängen zu konkreten Lösungen zum Verbreiten, Teilen und Wiederverwenden von Forschungsergebnissen. Berichte wie “Riding the Wave - How Europe can gain from the rising tide of scientific data” der High Level Expert Group on Scientific Data der Europäischen Kommission zeichnen eine Vision, bei der die Herausforderungen einer Diversität an Datenformaten, Menschen und Gemeinschaften durch die Anwendung technischer, semantischer und sozialer Eigenschaften der Interoperabilität vermieden werden. Diese Forschung adressiert derartige Herausforderungen aus einer technischer Perspektive. Fokus dieser Arbeit ist die Exploration eines neuartigen Ansatzes zur Unterstützung der Kuration (Sichtung und Korrektur) von Forschungsdaten mittels der Entwicklung einer Methodologie und mittels der Definition eines automatischen Datenkurationsprozesses in welchem Daten auf einfache Weise annotiert werden können. Ein Beitrag besteht in einem formalen Modell (COSI), welches die Integration großer Mengen an Metadaten erlaubt, welche als logische Konzepte behandelt werden können anstatt nur als Literale. Diese Konzepte werden in einer Ontologie definiert, welche, unter anderem, Inferenzen und Schlussfolgerungen ermöglicht. Der zweite Beitrag dieser Arbeit besteht in einer pragmatischen Lösung die es erlaubt, Metadaten on-the-fly zu annotieren. / Computational and information technology is one of the biggest advancement of the last century, a revolution that is influencing the way we approach social and technical problems in our day to day life. While these technologies have already influenced the research activity per sé, it is to be expected that these innovations will significantly influence the publishing and sharing of scientific results as well. So far, scientific publications have relied on limited result data attached inline in research paper publications. Establishments supporting research are pushing for concrete solutions that allow dissemination, share and reuse of research results. Reports such as “Riding the Wave - How Europe can gain from the rising tide of scientific data” of the High Level Expert Group on Scientific Data, European Commission (High Level Expert Group on Scientific Data, October 2010) presents a vision where the challenges of diverse data formats, people and communities are avoided due to the application of technical, semantic and social features of interoperability. This research is an effort to address similar concerns from a technical perspective. Focus of this research is the exploration of a novel approach on supporting research data curation by developing a method and defining an automated data curation process where data can be easily annotated. As a contribution, this work offers a formal model (COSI) that allows integration of plentiful metadata that can be treated as logic concepts and not merely as literals. These concepts are defined in an ontology that allows among other actions, inference and reasoning operations. The second contribution of this work is associated to a pragmatic solution that facilitates annotation of metadata on the fly. This solution is referred as sheer curation and shows how data can be annotated (based on COSI) and published while investigations are executed.

Indiana University-Purdue University Indianapolis (IUPUI) / Traditional resin luting agents generally have mechanical properties that are superior to the newer so-called “universal” self-etching/self-adhesive resin luting agents. However, recent reports indicate that some properties of these new luting agents have been improved, approaching those of the traditional etch and rinse resin luting agents. The objective of this study was to test some mechanical properties of four of these self-etching/self-adhesive resin luting agents [Maxcem Elite (ME), Multilink Automix (MA), RelyX Unicem (RU), SmartCem 2 (SC)] and compare them to a traditional etch and rinse resin luting agent [RelyX ARC (RA)] and a resin-modified glass ionomer luting cement [Fuji Plus (FP)], both of which have much longer histories of clinical success. By comparing the properties of the newer cements to the standards, it may be possible to determine how clinically successful the newer cements may be. The mechanical properties tested were flexural strength (FS) and shear bond strength (SBS). The FS test included making beams of each material, storing them in water for periods of time (24 hours and 90 days) and then performing a three-point bending test on a universal testing machine. The 90 day groups were thermocycled. The SBS test involved preparing human molar specimens, making flat dentin surfaces. Composite cylinders were fabricated, luted to the dentin surfaces with each of the materials tested, stored in water for periods of time (24 hours or 90 days), and then a knife edge shear test was performed on a universal testing machine. The 90 day groups were thermocycled. A Weibull-distribution survival analysis was performed. The results revealed significant differences in the FS of all materials tested at 24 hours. After 90 days and thermocycling, only SC and RA were not significantly different. At both time periods, FP had the lowest and MA the highest FS. The SBS results showed MA, RA, and RU to have the highest bond strengths; SC and ME the lowest at 24 hours. After 90 days and thermocycling, RA had significantly higher bond strength than all other groups; ME, FP and SC had the lowest. The self-etching/self-adhesive resin luting agents all performed at least as well as FP, with the exception of SC (SBS 24 hour). They did not all perform as well as RA, with the exception of SC (FS 90 day), MA (SBS 24 hour, FS 24 hour and 90 day), and RU (SBS 24 hour). The newer luting agents should expect to have clinical success, regarding flexural strength and shear bond strength, at least as good as resin-modified glass ionomer luting cements and approach the level of traditional etch and rinse resin luting agents.
